    Abstract: The invention provides a chiral iridium aqua complex which has good preservation stability, can be easily produced, and enables asymmetric transfer hydrogenation in a higher yield and with higher stereoselectivity. The chiral iridium aqua complex has the formula (1A): wherein Ra, Rb, Rc, Rd and Re are the same or different and each is a hydrogen atom, a methyl group, an ethyl group or a phenyl group, R1 and R2 are the same or different and each is an aryl group optionally having substituent(s), or R1 and R2 in combination show a C3-4 straight chain alkylene group optionally having substituent(s) to form a ring, R3 is an alkylsulfonyl group optionally having substituent(s) or an arylsulfonyl group optionally having substituent(s), R4 is a hydrogen atom, an alkylsulfonyl group optionally having substituent(s) or an arylsulfonyl group optionally having substituent(s), X is a monovalent or divalent anion, and n is 2 when X is a monovalent anion, or n is 1 when X is a divalent anion, and a production method of an optically active hydroxy compound using the complex.
